Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ECG electrodes are embedded in soft plastic material with fixed spacing, then the device structure is simple and easy to manufacture, but the device cannot be properly applied to curved body parts and has limited placement flexibility
Solution Approach 1:
The ECG device is divided into multiple independent electrode modules that can be separately positioned and attached. Each electrode can be independently placed on the body surface, allowing adaptation to curved surfaces while maintaining manufacturing simplicity through standardized modular components
Solution Approach 2:
The electrode spacing is made adjustable rather than fixed, allowing the device to adapt to different body shapes and sizes. The electrodes can be repositioned along conductive arms to optimize placement on curved surfaces such as the chest or breast area
2Device complexity
If ECG electrodes are placed with fixed spacing, then the device structure is simplified, but noise from myoelectricity and breathing is more likely to be captured causing signal distortion
Solution Approach 1:
The electrode spacing can be dynamically adjusted to optimize signal quality by increasing distance between electrodes to reduce noise pickup from muscle activity and breathing, while maintaining a simplified device structure through standardized adjustable mechanisms
3Ease of operation
If ECG electrodes are attached to the right or left side of the chest with short fixed spacing, then the device is easy to apply, but it cannot be applied to body portions with particular shapes or curves such as the breast portion
Solution Approach 1:
The device uses separate, independently positionable electrode modules that can be distributed across different body contours, enabling application to curved surfaces like the breast area while maintaining ease of application through simple attachment mechanisms
Solution Approach 2:
The electrode spacing parameter can be changed to accommodate different body shapes and sizes, allowing the same device to be easily applied to various anatomical variations including curved surfaces
